However, being one of the largest companies on planet and always thinking about long term strategy instead of quick gains, Microsoft doesn't really need to sell Bing. Their online division might be losing money on paper, but it's more of a supportive division anyway. Don't forget that they also work on services like MSN Messenger, their news sites, and very wide array of other services and software like Azure. They support Microsoft's and Windows' strong brand name and are also a division of innovation that will enable Microsoft's success in the future as more and more services move online. People on slashdot always complain that companies aren't thinking long term but instead just try to get quick profits. Well, Microsoft is one of those companies that only think long term. In fact, most of what Google does is to gain quick profit and ditch the projects that fail with that. Just see how many projects Google quickly and silently cancels compared to Microsoft.
Sony's own website makes mention of the supported devices requiring a touch screen, so, that kind of rules out the PS3:
You can develop games and applications that utilize physical buttons and touchscreen by using the integrated development environment (IDE) and simulator for the PC which are both included in the PlayStation(R)Suite SDK. [emphasis mine]
Sorry, but that just says you can develop games for devices that utilize physical buttons and/or touchscreen. That really doesn't sound like it's required to have touch capability.
For me, Google is largely the same. That is how they make money. I much more happily pay for a piece of software or service when I know exactly what I get, and that I get it good price without foul play. Google and other marketers twist this. Nobody has time to completely research or get to know what they buy or what's available. Those marketers rely on that weakness, and in turn you are getting screwed. Do you really want to be thinking all the time if someone is screwing you over? It sucks.
